Hastelloy C4 Plate in Chennai for Hydrochloric-Acid Process Equipment

Hastelloy C4 Plate in Chennai for Hydrochloric-Acid Process Equipment

Hastelloy C4 plate and sheet for hydrochloric-acid systems in Chennai chemical plants. C4 is a low-silicon, titanium-bearing nickel-chromium-molybdenum alloy made to stay stable after heating, so the heat-affected zone and hot chloride service are less prone to grain-boundary precipitates. Maintenance and fabrication teams in Manali, Ponneri and the North Chennai chemical belt specify it for HCl lines, vessels and equipment that is welded or stress-relieved during fabrication. Ganesh Metals cuts C4 plate to size and has been a high-nickel alloy stockist, supplier and processor in Mumbai since 1992.

We provide direct door delivery to your company in Chennai. C4 plate is cut and packed at our Mumbai shop and supplied from our Mumbai stock to Manali, Ponneri, Gummidipoondi, Ennore or Ambattur. Send the HCl strength, temperature and whether the vessel will be welded or heat-treated, and we will confirm C4 is the right grade before quoting.

Hastelloy C4 plate specifications

Hastelloy C4 (UNS N06455, W.Nr 2.4610): plate, sheet and strip ASTM B575 / ASME SB575, in the solution-annealed condition.

The same grade is also supplied as bar to ASTM B574, seamless pipe to B622, welded pipe to B619 and welded tube to B626, plus fittings to ASTM B366 (WPHC4) and flanges to ASTM B564.

Pipe, tube and flanges: sizes confirmed per enquiry, from Mumbai stock.

How C4 differs from C276 and C22: C4 is the C-family grade chosen for hydrochloric acid and for thermal stability during welding or intermediate-temperature exposure. C276 is the general mixed-acid and wet-chlorine workhorse; C22 is preferred for strongly oxidising streams and much pharma duty. See also the C276 vs C22 guide.

Typical chemistry: Cr 14.0–18.0%, Mo 14.0–17.0%, Ti 0.70% max, Fe 3.0% max, C 0.015% max, Si 0.08% max, nickel balance. Density about 8.64 g/cm³.

Minimum properties, ASTM B575 solution-annealed plate: tensile 690 MPa, yield 276 MPa, elongation 40%.

Equivalents: W.Nr 2.4610. The UNS number N06455 on the MTC is what your inspector should check.

C4 plate and sheet: how it is supplied

HCl plant work usually needs C4 in liner, patch and vessel-cut sizes rather than a full mill plate. We cut sheet and plate to your list, punch circles for blanks and covers, and slit strip for lining or overlay. Each cut piece keeps the parent-plate heat number for the inspection file. Work out weights with the metal weight calculator.

Where C4 plate is used in Chennai chemical plants

Hydrochloric-acid handling in Manali: C4 plate for storage and transfer vessels, coolers and nozzle repairs on HCl-wetted equipment.

Chlorination and hydrochlorination units in the North Chennai belt: C4 for hot HCl-bearing gas and liquid service where thermal stability after welding matters.

Acid-recovery and hydrochloric pickling systems: C4 sheet for tanks, hoods and heating-surface panels.

Chemical intermediate plants in Ponneri and Gummidipoondi: C4 plate for reactors and receivers whose main medium is HCl.

Fabrication shops in Ambattur building this equipment: C4 plate for shells, covers and liners cut to the shop drawing.

Why Manali and North Chennai plants order C4 plate from Ganesh Metals

High-nickel alloy stockist, supplier and processor in Mumbai since 1992.

The mill's original EN 10204 3.1 test certificate is passed on with every supply, with heat-number traceability.

ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certified.

C4, C276 and C22 are PMI-checked on every lot, because the three grades look alike once they are cut.

Patch and liner sizes are cut from stock plate, so an HCl repair does not mean buying a full sheet.

If mixed acids or a strongly oxidising stream means C276 or C22, we will say so before you order C4.

FAQs — Chennai

Do you supply Hastelloy C4 plate to Manali?

Yes. We send C4 plate, sheet and strip to Manali, Ponneri, Gummidipoondi, Ennore and Ambattur, supplied from our Mumbai stock. We provide direct door delivery to your company in Chennai.

How long does delivery to Chennai take?

That depends on the transporter and route. We confirm the dispatch plan with you when the order is placed.

C4, C276 or C22 for a hydrochloric-acid vessel?

C4 is the usual C-family choice when HCl is the main medium and the vessel will be welded or exposed to intermediate temperatures. C276 covers mixed acids and wet chlorine; C22 is better for strongly oxidising streams. Send the acid strength and temperature and we will help you compare. See C276 plate in Chennai and C22 plate in Chennai.

Can you cut C4 plate for a welded HCl vessel?

Yes. Send the drawing or cutting list and the thickness. We cut plate and sheet to size and mark the heat number on each piece, so the inspector can trace the parent plate.

Will C4 plate come with a 3.1 certificate for plant inspection?

Yes. Every supply comes with the mill's original EN 10204 3.1 test certificate, and heat numbers are marked on each piece. Call +91 22 6636 2372 or WhatsApp +91 99872 73700 to discuss your use.
